		CKEditor Sample &mdash; Adding Event Handlers
	</h1>
	<div class="description">
	<p>
		This sample shows how to add event handlers to CKEditor with PHP.
	</p>
	<p>
		A snippet of the configuration code can be seen below; check the source code of this page for
		the full definition:

	<pre class="samples">&lt;?php
// Include the CKEditor class.
include("ckeditor/ckeditor.php");

// Create a class instance.
$CKEditor = new CKEditor();

// Path to the CKEditor directory.
$CKEditor->basePath = '/ckeditor/';

// The initial value to be displayed in the editor.
$initialValue = 'This is some sample text.';

// Add event handler, <em>instanceReady</em> is fired when editor is loaded.
$CKEditor-><strong>addEventHandler</strong>('instanceReady', 'function (evt) {
	alert("Loaded editor: " + evt.editor.name);
}');

// Create an editor instance.
$CKEditor->editor("editor1", $initialValue);

				<strong>CKEditor requires JavaScript to run</strong>. In a browser with no JavaScript
				support, like yours, you should still see the contents (HTML data) and you should
				be able to edit it normally, without a rich editor interface.
